Most reloading manual list a start and max load along with velocity on a test rifle etc.
If someone finds a good accuracy load near max who's to say that's a hot load. I'm sure some would like to rewrite the manual change velocity but we can't.
Myself I look for accuracy and I can't change the velocity I get with that load what ever it is.
I may have couple loads that shoot good in my rifles the one I pick to use is the one with the highest velocity from the manual loads I'm using. You can always alter that with longer barrel,different twist,rifling etc.
I don't see any problems with someone loading up to published max loads if that how they want to reload and I'm sure they read the reloading manuals on what to watch as to pressure.
